Public bug reported:
when the VM is in SHELVED_OFFLOADED state the VM doesn't exist
physically on any compute node so resetting the state to active or error
might cause the DB inconsistency and also make unshelving difficult.

Not just unshelve, we cannot perform any VM operation as VM doesn't
exist anywhere.
